Reimplemented in Compiler::ExprParser, Compiler::LineParser, Compiler::ControlParser, CSVWorld::ScriptHighlighter, Compiler::FileParser, Compiler::ScriptParser, Compiler::SkipParser, and Compiler::StringParser.

void Compiler::Parser::reportEOF ( ) [protected]

Report an unexpected EOF condition.

void Compiler::Parser::reportError	(	const std::string &	message,
		const TokenLoc &	loc
	)		`[protected]`

Report the error.

void Compiler::Parser::reportSeriousError	(	const std::string &	message,
